What is Esbriet?
Esbriet (pirfenidone) is used to treat a lung disease called idiopathic pulmonary fibrosis (IPF). IPF causes scar tissue to form deep within your lungs. The scar tissue thickens and becomes stiff or thick over time, which can make it harder for your lungs to work. Decreased lung function can make it hard for you to breathe. Other medical problems can occur when your brain, heart, and other organs do not get enough oxygen.
The cause of IPF is often unknown, but this condition is a progressive disease that can be fatal.
Esbriet is not a cure for IPF, but this medicine may slow the progress of this disease.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
